The show “Top Boy” has had an interesting life. The gritty British drama about drug dealers on a low-income housing estate was originally cancelled in 2014 — until an unlikely saviour stepped in. Turns out, Drake was a big fan of “Top Boy” and he was able to get the show back on the air for three more seasons. Now, the drama is back again, but in a different form: a novel. “Top Boy” creator and showrunner Ronan Bennett joins Tom to talk about the history of the series, and why he wanted to write a book based on the show.
